Mission can not be fulfilled / rocket / Scanning

The mission "Destroy 50 Floodlights in a Single Run" can not be satisfied.

Rocket: I can hold a total of 60 missiles. If I (have no picture) in the view (ie in the spaceship) top 20, middle 20 and bottom 20 have, and the top are all, no missiles appear to me in the game. I manually switch (key 3) that he should take the other missiles from the Middle Slott.I hope you understand what I mean!?

Suggestion Scanner: If I have already scanned a sector, should this can not scan again. This happens from time to time me. Is stupid because a scanning probe then routes.
